24KtG vs. new FM Songs

[HoursAndHours]

So, which (if any) demos do you think are most likely to be passed over for 24KtG in favor of finding a home on the new Fleetwood Mac album, and why? Or do you think she'll write all new material for FM, because of what she's doing for the new solo album?

My most likely guesses:
1. If You Were My Love Wasn't this one almost on Mirage?
2. All The Beautiful Worlds According to this site, it was recorded for SYW...
3. Any/all of the Rhiannon Songs, especially if this is to be the last FM record as some have speculated.
